Liam Aharon 4a293bc5a2 Enforce consistent and correct toml formatting (#2518 )

Using taplo, fixes all our broken and inconsistent toml formatting and
adds CI to keep them tidy.

If people want we can customise the format rules as described here
https://taplo.tamasfe.dev/configuration/formatter-options.html

@ggwpez, I suggest zepter is used only for checking features are
propagated, and leave formatting for taplo to avoid duplicate work and
conflicts.

TODO
- [x] Use `exclude = [...]` syntax in taplo file to ignore zombienet
tests instead of deleting the dir

DO NOT USE IN PRODUCTION

The produced values do not fulfill the cryptographic requirements for random numbers. Should not be used for high-stake production use-cases.

Randomness Module

The Randomness Collective Flip module provides a random function that generates low-influence random values based on the block hashes from the previous 81 blocks. Low-influence randomness can be useful when defending against relatively weak adversaries. Using this pallet as a randomness source is advisable primarily in low-security situations like testing.

Public Functions

See the Module struct for details of publicly available functions.

Usage

Prerequisites

Import the Randomness Collective Flip module and derive your module's configuration trait from the system trait.

Example - Get random seed for the current block

use frame_support::traits::Randomness;

#[frame_support::pallet]
pub mod pallet {
    use super::*;
    use frame_support::pallet_prelude::*;
    use frame_system::pallet_prelude::*;

    #[pallet::pallet]
    pub struct Pallet<T>(_);

    #[pallet::config]
    pub trait Config: frame_system::Config + pallet_insecure_randomness_collective_flip::Config {}

    #[pallet::call]
    impl<T: Config> Pallet<T> {
        #[pallet::weight(0)]
        pub fn random_module_example(origin: OriginFor<T>) -> DispatchResult {
            let _random_value = <pallet_insecure_randomness_collective_flip::Pallet<T>>::random(&b"my context"[..]);
            Ok(())
        }
    }
}
